9 Claims. (Cl. 139-260) This invention relates to improvements in thread control mechanisms for weft replenishing looms weaving with diverse types of filling wefts or threads having different elastic qualities, and it is the general object of the invention to provide means whereby the outgoing thread, whether it be elastic or nonelastic, of an outgoing bobbin is prevented from being drawn into the shed after it has been cut by the usual thread cutter at the shuttle eye on a weft replenishing beat of the loom.

The type of loom referred to above generally employs a vertically shifting shuttle box mounted at each end of the loom on a backwardly and forwardly reciprocating lay, each box comprising at least two shuttle cells for movement to active position one at a time to receive into or eject therefrom one of a number of shuttles used during loom operation. Certain of these shuttles carry bobbins having nonelastic filling threads, such as light weight cotton threads, and certain of these shuttles carry bobbins having elastic filling threads made up of a rubber core around which a cotton thread is wound helically. During weaving, the shuttle containing the cotton thread will lay a pick of filling thread in the shed with the thread under very little tension, as is well-known in the art. When the shuttle containing the elastic filling thread is in the first part of its flight, that part of the thread extending from the fabric to the shuttle will contract, after which, during continued shuttle flight, it will be stretched to a high degree before it can unravel from the bobbin. In this usual manner the elastic thread is laid in the shed under considerably more than the tension referred to above. An example of the type of fabric being woven with cotton and so-called rubber threads is bathing suit material in which the cotton and rubber threads are laid alternately in their respective sheds, this alternation being only one of many picking sequences to which the present invention can be applied.

When replenishment of an exhausted bobbin in a shuttle is to occur, the outgoing thread of the bobbin will extend in a straight line from the top cell of the shuttle box on the magazine side of the loom to the selvage of the fabric being woven. In some instances, the outgoing thread will be under considerable stretch and tension because of its elasticity, and in other instances the' outgoingthread, such as the cotton, will be under very'little tension, if any. Because of the difference in the elastic qualities between the two threads, and because no indication is given as to which of these threads is the outgoing one, considerable difficulty has been experienced in providing simple means to control and remove either one of these threads during a weft replenishing operation. This difliculty quite often leads to imperfections in the fabric being woven because of the inabilityof present-day mechanisms to effectively control and remove elastic and nonelastic threads to prevent them from entering the shed when they are cut bythe said usual thread cutter. It is, therefore, an important object of the presentinvention to overcome this difliculty and to prevent entry of an outgoing thread into a M ice shed by providing simple thread control means to have a simultaneous thread clamping and trapping operation whereby one type of thread is clamped and another type is trapped independently of each other and before either type is cut at the shuttle eye.

Another object of the invention is to provide thread control means effective to clamp the outgoing elastic thread and efiective to trap the outgoing nonelastic thread, depending upon which thread extends from the top cell to the fabric, before either one is cut at the shuttle eye.

Another object of the invention is to provide the thread control means with pneumatic thread removing means and a thread clamping member cooperating with each other effective to clamp the outgoing elastic thread and ineffective to clamp the outgoing nonelastic thread but effective to trap the latter thread on replenishing beats of the loom.

It is another object of the invention to provide thread control means, movable from a forward normal position to a rear position and back again incident to a weft replenishing operation, having a narrow, vertically extending, thread intake mouth and a vertical, thread clamping member, the rear part of which extends into the mouth to coact with one of the sides thereof to clamp the elastic thread, said rear part having a portion remote from said side to provide a space therebetween to receive and trap the nonelastic thread when the clamping member is in clamping or closed position.

It is another object of the invention to provide primary control means mounted on the thread removing means to move the clamping means to nonclamping or open position as the thread control means moves rearwardly when the magazine is set for a replenishing operation, said primary means being adjustable to vary the time of opening of the clamping member.

Still another object of the invention is to provide actuator means engageable by the primary control means to cause positive movement of the clamping member to nonclamping or open position when the thread control means moves rearwardly, said actuator means being laterally adjustable with respect to the primary control means for engagement therewith at different points along said primary means to vary the amount of movement of the clamping member when the primary control means engages the actuator means.

A further object of the invention is to provide secondary control means to move the clamping member to clamping or closed position when the thread control means is moved forwardly from its rear position by the advancing lay incident to a weft replenishing operation.

A further object of the invention is to provide the thread control means with a tubular member having thread guiding means thereon facing rearwardly of the loom to guide the outgoing thread downwardly and forwardly as the latter advances with the lay so that the outgoing thread will pass beneath the tubular member after which it will move up between the tubular member and the clamping means when they are in their rear position, whereupon continued forward motion of the lay will move the thread control means forwardly to effect clamping or trapping of the thread by the secondary control means, depending on whether the outgoing thread is elastic or nonelastic.

- It is a further object of the invention to make and mount the clamping member in such manner that when the highly tensioned outgoing rubber thread is clamped and then cut at the shuttle eye, it will snap against the member, after which it will be drawn into the tubular member and away form the loom to prevent entry of the thread into the shed.

n It is another object of the invention to provide means lar member and the clamping member when the top cell shifts vertically to transfer or weft replenishing position.

Other objects of the invention will appear as the description proceeds, and in order that the invention may be clearly understood reference is made to the accompanying drawings which illustrate by way of example two embodiments of the invention, and in which:

Referring particularly to Fig. 1, the loom frame 1 supports a magazine, generally indicated at M, having a top rocking shaft 2, a lever 3 fixed thereto and a connector rod 4 depending from lever 3. The magazine frame supports a transfer latch for cooperation with a transfer dagger 6 on weft replenishing beats of the loom. Latch 5 is operatively connected to a lower end of a rod 7, the upper end of which is connected to a lever 8 fast on shaft 2. A transferrer arm 9 operatively connected to latch 5 is pivoted as at 11 to the magazine frame. The lay L is mounted for back and forth reciprocation during loom operation, and supports a vertically shifting shuttle box, generally indicated at "B, at the magazine end of the loom. Shuttle box B has upper and lower shuttle cells 12 and 13 respectively to receive into or eject therefrom weft carrying shuttles, one of which is shown at 14. Although in the present instance more than one shuttle will be used during weaving operations, and that certain of the shuttles will carry elastic filling threads, and that others will carry nonelastic filling threads, it is to be understood that the invention is not limited in use only with multiple shuttles but that the'invention is also applicable to single shuttle weaving.

Incident to a weft replenishing operation, weft exhaustion will be indicated by the usual weft feeler (not shown) in any one of the well-known ways as the box B is rising while the lay is in the forward part of its stroke. An indication ofweft exhaustion will effect setting of the magazine for, a weft replenishing'operation by rocking of shaft 2 in a direction to raise counector rod 4, for a purpose to be described hereinafter, and lower rod 7 to raise the latch 5 for engagement with dagger 6 on the next forward movement of the lay following indication of weft exhaustion and'while the shuttle box B is in high or transfer position. Upon engagement of the dagger with the latch, the latter will be moved forwardly by the advancing lay to rock arm 9 counterclockwise, Fig. 1, around pivot 11 to transfer reserve bobbin into the exhausted shuttle. 'It is to be noted that the invention is neither limited to vertical shifting shuttle boxes at both ends of the loom but that it can be 'used'with the so-called 1x 1," 2x 1, 4 x 2, etc. box motions, nor is it limited to replenishment on the next beat following indication of weft exhaustion, since the invention will operate satisfactorily when an indication is stored and replenishment is to occur on a beat subsequent to the next beat following indication of weft exhaustion. It is believed that a further detailed description of the operation of the magazine, the weft feeler, the lay, the box motion and the transferring of a bobbin is unnecessary since these operations are all well-known in the art, and that the parts above described operate in the usual way and form no part of the present invention except as described hereinafter.

In carrying the preferred form of the invention into effect, see Figs. 1 to 3, a stand 16 is bolted as at 17 to the magazine and supports a bell crank lever 18 pivoted as at 19 at the rear of the stand 16. Lever 18 has a depending bifurcated arm 20 and a rearwardly extending arm 21 which is operatively connected to the lower end 22 of the previously described rod 4. A lever 23 is pivoted on arm 20 as at 24. Lever 23 has a bearing 25 to support a vertically adjustable thread remover, generally indicated at R, held in position by set screw 26.

The thread remover R has a tubular member 27 closed by a plate 28 at the bottom thereof and connected at its upper end to a flexible tube 29 which in turn is connected to a source of pneumatic power to create subatmospheric pressures within the member 27. Such a source is shown, for instance, in Patent No. 1,212,681 issued to Rhoades whereina double acting pump is driven by the m to create said pressures. It is to be understood that this pump is only one of many ways to create subatmospheric pressures in tube 29 and that the invention is not limited to the use of this particular type pump. Member 27 has fixed thereto in any.approved manner upper and lower bearing plates. 30 and 31 respectively which support a rockable vertical stub shaft 32, the lower end of which has a clamping member 33 mounted thereon and the upper end of which has a collar 34 adjustably secured thereto by a set screw 35; One end of a rod 36 is screw threaded into collar 34 and extends laterally therefrom in a direction toward stand 16. Intermediate the ends of the shaft 32 a collar 37 is held in position thereon by a set screw 38 and is adjustable angularly about the shaft 32. A spring 40 surrounds the shaft 32 between the collar 38 and the lower bearing plate 31. One end of the spring is connected to the collar 38, as at 41, Fig. 3, and the other end of the spring is connected to the plate 31 as at 42, Fig. 2. Collar 37 is adjusted on shaft 32 such that spring 40 will exert a force in a direction to turn mem ber 33 in a counterclockwise direction as viewed in Fig. 6, and also exert a force in a direction to lift the member to hold surface 43 thereof against undersurface 44 of bearing plate 31. Thus it is that member 33 is held firmly in clamped or closed position butyieldable to nonclamping or open position. Clamping member 33 has a rear part 45 which extends into a vertical mouth 46in tube 27 to engage side 47 of mouth 46 because of the force exerted by spring 40, see Figs, 3, ,6. and 8. An upper rear portion 48 extendsfrom part 45 but is out of alignment therewith such that when part 45 engages side 47 portion 48 will be remote from side 47' to providea spajce 49,'Fig. 8, fora purposeto be described. The tubular member 27 has fixed thereto 'a fin-like member 50 having a rearwardly facing convex surface 51 for engagement with the thread of an outgoing bobbin, as will be explained hereinafter. The'tubular member 27 and the thread clamping and trapping member may be con ber 53 has secured thereto a bolt 55 having a head 56 for engagement with the rod 36 when the magazine is set for a Weft replenishing operation. Bolt 55 is adjustable laterally with respect to rod 36, see Fig. 3, in order that head 56 be capable of engagement with rod 36 along different points of the latter to vary the amount of movement of part 45 away from side 47 of mouth 46. In this way the optimum position of clamping member 33 can be attained to facilitate the entry of an outgoing thread between the tubular and clamping members 27 and 33 respectively. Bolt 55 may be considered as actuator means for rod 36. By adjusting collar 34 angularly about shaft 32, the primary control means can be set for early or late engagement with the actuator means to vary the time of movement of clamping member 33 to nonclamping or open position.

When a weft replenishing operation is to occur, the rocking shaft 2 will turn, as explained above, to set the magazine for transfer and, at the same time, will effect lifting of rod 4 to rock lever 18 clockwise, as viewed in Fig. 1, to move the thread control means and the primary and secondary control means rearw-ardly to the position shown in Figs. 13 and 14. While rod 36 is moving rearwardly, it will engage head 56 of bolt 55 and clamping member 33 will be rocked clockwise, as viewed in Fig. 9, away from the side 47 of mouth 46 to nonclamping or open position. It is to be understood at this point that indication of weft exhaustion had been given, that the shuttle box B is in its high position, and that an outgoing thread extends in a straight line from cell 12 to the fabric F. As the lay advances the thread will advance therewith and engage the convex surface 51, see Figs. 13 and 15. Continued forward motion of the lay will cause the thread to cam down the surface 51, beneath plate 28, see dotted line position of Fig. 15, after which the thread will move between the mouth 46 and the member 33 as shown in Fig. 9. This movement will occur, as explained hereinafter, whether the thread is nonelastic, such as cotton, or whether the thread is elastic, such as the rubber cored thread referred to above.

Further advancement of the lay will cause the head 57 of a screw 58 on the lay to engage a laterally extending stud 59 fast with respect to lever 18. When the head 57 engages the stud 59 continued forward motion of the lay will effect movement of the tubular and clamping members forwardly, and rod 36 will leave head 56 to permit spring 40 to turn the clamping member 33 counterclockwise from the position shown in Fig. 9 to that shown in Fig. 10, to clamp or trap the outgoing thread, depending on whether the thread is elastic or nonelastic.

When the outgoing thread is of the elastic type, it will be under considerable stretch and tension and as it passes the bottom of tubular member 27 it will snap up between the mouth 46 and the clamping member 33 to be within the range of part 45 and side 47 and will be clamped thereby when the tubular and clamping members are being moved forwardly. In the case of the cotton or nonelastic thread, as it passes the tubular member 27 it will be drawn upwardly into the mouth 46 by the subatmospheric pressures created in the tubular member. Since the-nonelastic thread is under very little tension, if any, the pressures are of sufiicient strength to lift the thread to place it in space 49 between side 47 and portion 48, see Fig. 8, and when the clamping member moves to clamping position the cotton thread then will be trapped in space 49 between portion 48 and side 47.. The dif ference between clamping of one kind of thread and trapping of another is important in the present application because of the fact that the cotton thread is usually lightweight and delicate, and in order to avoid breakage or fracture thereof it cannot afford to be clamped or pinched as can the rubber thread. However, it is to be understood that the present invention is not limited to use y c t n pr rubbe h e b t; ha it 4 operate satisfactorily with filament threads, woolen or worsted threads, or a variety of combinations thereof.

Referring to Fig. 9, the usual filling thread cutter 61 and the usual temple cutter 62 are shown in their normal position. A thread T extending from cell 12 to the fabric has a part thereof between the tubular member 27 and the clamping member 33, having reached that position as described above. The position of the thread control means shown in Fig. 9 corresponds to the dotted line position shown in Fig. 7, Le. the member 33 will be in nonclamping or open position. Thread T, in this instance, is the elastic thread which, because of its resiliency and high tension, must be clamped before cutter 61 has the usual cutting operation to sever the thread at the shuttle eye to prevent snapping of the thread into the shed in order to avoid imperfections in the fabric. As stated before, advancement of the lay moves the tubular member 27 forwardly and prior to the reaching of socalled front center position, spring 40 will cause clamp- I ing member 33 to move to clamp the thread T, see Fig. 10 which, shortly thereafter, will be severed by the cutter 61. After the thread has been cut that part of the thread T1 extending from the mouth 46 to shuttle cell 12 will snap against member 33 and thus be prevented from entering the shed, whereupon thread T1 will be drawn into the tube by the pneumatic pressures therein, see Fig. 11. That part of the thread extending from the mouth tothe fabric P will be subsequently cut at the selvage by the temple cutter 62 on some later beat of the loom. After the temple cutter operates the thread will remain clamped until the member 33 is opened again, after which the balance of the thread will be drawn into the tube and away from the loom.

With reference to Fig. 12 the thread TC shown therein is of the cotton or nonelastic type and after the thread has been severed at the shuttle eye, as described with respect to the elastic thread, the thread extending from the mouth 46 to the shuttle cell 12 will be drawn into the tubular member as was the case with the elastic thread. However, in the operation of the clamping member with respect to the nonelastic thread, thread TC will be trapped as described hereinbefore and shown in Fig. 8 before the cutter 61 operates to sever the thread, after which that part of the thread from the mouth to the shuttle will be drawn into member 27. Subsequently the temple cutter 62 will cut the thread at the selvage but this thread will not be able to fall to the floor or away from the tubular member because of its being trapped in space 49 between side 47 and portion 48. Once the nonelastic thread is cut by the temple cutter it will be drawn into the tube and away from the loom.

In the modified form of the invention, shown in Fig. 16, the thread control means, the primary, secondary and actuator means will be the same and operate in the same manner as in the preferred form of the invention. However, the motion of the boxes under the magazine differs somewhat from the motion in the preferred form in that during a replenishing beat of the loom, top cell 64 will separate from lower cells '65 and 66 to place the thread directly between the month 46 and the clamping member 33. It will be noted that when the tubular member 27 is moved rearwardly, mouth 46 will take an oblique position and this is also true in the preferred form of the invention with respect to the outgoing thread to facilitate the entry of the thread between the mouth and the clamping member and consequently into the tubular member. Cells 64, 65 and 66 and the operation thereof form no part of the present invention except in that the thread is lifted directly by a shuttle cell to a position conducive for clamping, or trapping, and removal of a thread thereafter. The operation of these cells can be readily understood by reference to Litchfield Patent No. 2,777,473.

From the foregoing it will be seen that the invention provides simple means whereby diverse filling threads h v nssti s ente a t s ss itia s i vars ty sstml sd and removedfrom the loom to prevent entry thereof into the 'warp shedwhen a Weft replenishing'operation is to take place. Also, means have been provided to clamp the outgoing elastic threadand to trap the outgoing nonelastic thread, depending upon which thread is extending from the shuttle cell to the selvage at the time replenishing is to occur. It will also be seen that simple means have been provided to move the clamping member to nonclamping or open position and to return the same to clamping or closed position. i The clamping member 36 also acts as a buffer plate to prevent the outgoing thread from entering'the warp shed or wrapping itself around the tubular and clamping members and to facilitate removal of the thread by the subatmospheric pressures in the tube 27. Also, guide means have been provided to assist the outgoing thread to reach a position between the mouth and the member 33 whereupon the thread is clamped or trapped, as the case may be, and then removed from the loom to prevent the thread from entering the shed. Moreover, means have been provided whereby the time of opening and closing of the member 33 may be varied as well as the amount of movement of the memher. In the modified form of the invention it will be seen that by the simple expedient of lifting a shuttle cell the outgoing thread is placed directly between the mouth and the clamping member, the placing being facilitated by the fact that the tubularmember, and consequently the mouth, is oblique with respect to the thread.

Having now described and ascertained the nature of the invention and in what manner the same is to be performed, it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention, and that the invention is not limited to the details herein disclosed, but what is claimed is:
